Calculating phase velocity of TM01 mode in HFSS driven model

[adiha]

Hi,

I'm trying to plot the phase velocity of the propagating TM01 mode in HFSS.

I'm using single frequency, and according to numerical analysis, the structure should change the phase velocity along a line (for example, z-axis).

Any ideas on how to do it?

Thanks!

Welcome adiha,

Perhaps extract it from S21 for varying lengths of the line?

Welcome adiha,

Could you please elaborate? how do I extract S21 (phase) from my model? All the examples I saw included frequency sweep, and I have only single frequency.

Thanks!
